Outbuilding Fan Vibrometers: Around 4 days ago, EY_FAN1_470_1 jumped from 0.31 to 0.33 counts (3rd screenshot zoomed in illustrates this). Compared to last week, this is a new increase. Compared to last month, it is within normal fluctuation (and rather, last week was just particularly low vibration). However, prior fluctuations were gradual unlike this sudden, glitch-form spike.

CS Fan Vibrometers: No changes of note compared to last week.
